Each transistor includes a 1 kΩ base resistor (R1) and a 10 kΩ base-emitter resistor (R2), eliminating the need for external bias components in low-side switching and driver applications. The device is rated for a collector-emitter breakdown voltage of 50 V and a continuous collector current of 500 mA, with a maximum power dissipation of 330 mW. ## NRND — plan for a last-time buy or alternate This means the part is still available for existing production but is not intended for new design-ins. Buyers should evaluate a last-time-buy window or qualify a pin-compatible alternative from the BCR523 family for ongoing builds. ## Switching performance and saturation With a transition frequency of 100 MHz and a Vce saturation of 300 mV at 2.5 mA base current and 50 mA collector current, this dual transistor is suited for medium-speed switching up to several megahertz. The minimum DC current gain of 70 at 50 mA, 5 V ensures consistent drive capability across the operating range.","metaTitle":"Infineon BCR523UE6433HTMA1 Dual NPN Pre-Biased Transistor","metaDescription":"Infineon BCR523UE6433HTMA1 dual NPN pre-biased transistor in SC-74 (SOT-457) package. 50 V Vce, 500 mA Ic, 330 mW.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"330mW","Mounting Type":"Surface Mount","Package / Case":"SC-74, SOT-457","Product Status":"Not For New Designs","Transistor Type":"2 NPN - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Base Product Number":"BCR523","Resistor - Base (R1)":"1kOhms","Frequency - Transition":"100MHz","Supplier Device Package":"PG-SC74-6","Resistor - Emitter Base (R2)":"10kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 2.5mA, 50mA","Current - Collector (Ic) (Max)":"500mA","Current - Collector Cutoff (Max)":"-","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 50mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1409","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/bcr523series.pdf?folderId=db3a30431428a373011440769fd70304&fileId=db3a30431428a3730114407c929c0309","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR523UE6433HTMA1 obsolete?","answer":"It is not fully discontinued but is not intended for new design-ins.
